RÉSUMÉ

An anisotropic subgrid-scale model with five terms depending on strain and rotation rate is investigated. Single terms and the combinations of two of the five terms are tested in a turbulent channel flow at a turbulent Reynolds number of Reτ = 395. The model constants, one for each term, are determined dynamically. Some models with a combination of two terms achieved slightly better results than the single term models with about 25% additional computational costs compared to the Germano model.
